Is there anyway to get a list of the filters necessary for VPN

Here is my scenario: I have a Master VPN server running BM 3.7 and 2
slave servers (1 running BM3.7 and the other running BM 3.6).

The communication between the 2 3.7 servers is working just fine. The BM
3.6 server, while it is communicating, is taking a fair amount of time to
finish file transfers. the original transfer begins and seems to run just
fine, but closing the file and connection can take up to a minute.

At last read, Craig's book says that no additional VPN filters are needed
on a BM36EE server and I have added the necessary filters on the BM37

Any other ideas are greatly appreciated.
